Glad it worked out

Glad you got it fixed.

We do get a lot of power supply problems with all types of power supplies.  Flex radios require 25A or better.

The one test you need to do is have the radio transmitting in a constant carrier mode (like FM) into a Dummy Load.  Now, we a voltmeter you trust to measure the voltage on the back of the radio and make sure it is about 13.5V or higher.  Again, while transmitting.

Since the radio draws over 20amp on TX, imagine if you had 0.1 ohm resistance somewhere between the power supply and the radio.  How much voltage do you think you could lose?  

I can give you the answer if you wish, but give it some thought.

Hi Mick,

Sounds like you got it sorted.  I will say that you would be best to hardwire your radio to your router using shield network cable and perhaps some RFI cores on the cable ends for good measure.

A vast majority of "strange" issues with Flex Radios have been resolve with better networking.

Another option would be to do a fiber link between where your radio is and your router.  More expensive, more pieces to be buy but the benefits are zero RFI pickup on the fiber cable which can be very long.  And isolation from any kind of spike that might come over ethernet.

I have my radio and its switch connected via fiber just for safety sake.
